‘Alexa, please switch the boiler on’

Like countless others with similar properties,

Guildford homeowner Tony Croke invested

in extensions to his 1930s semi-detached

house, adding a fourth bedroom and a second

bathroom upstairs plus a new kitchen and more

living space downstairs.

The planned improvements triggered a rethink

on plumbing and heating arrangements – and

the decision to replace a 15-year-old gas boiler

with the latest technology.

“The boiler had to be relocated anyway, so it was

a sensible choice to install a new one,” says Tony.

“And the old boiler was not the condensing

type, so it was noisy and – by modern standards

– very ineffi cient.”

He chose a 35kW gas condensing boiler from

Daikin, recognising its potential to reduce

operating costs and emissions, while meeting

the family’s new heating and hot water

requirements much more quietly than the old

boiler.

Daikin’s three gas condensing boilers, from 24kW

to 35kW, are all A-rated in terms of space and

water heating effi ciency.

Tony says: “It quickly settles down to the

operating level necessary to achieve the desired

indoor air and water temperatures. But as the

boiler is compact enough to fi t in a kitchen

cupboard, we’ll hardly know it’s there.

“It is designed for use as a system boiler or as a

combi boiler – and we are using it in both ways.”

A system boiler heats domestic hot water

indirectly, while a combi boiler provides hot

water on demand – which can save space by

removing the need for a hot water cylinder and

avoid the cost of keeping a tankful of water hot.

Tony says:

“Our new boiler operates

as a system boiler to serve

our existing radiators, the

underfl oor heating zone

downstairs in the extension

and the coils in our hot water

cylinder.”

“We have a power shower, which works well with this plumbing

arrangement, but the gravity-fed shower in the other bathroom

has always been a great disappointment. So we took the

opportunity to connect this directly to the combi output of the

new boiler.”

It’s not only showering that’s proving more popular. The Croke

family’s new boiler has a volt-free Nest controller, which is

connected to the internet.

Tony says: “There are other benefi ts of online control, including a

phone app for setting timer, temperature and on/off controls.

“One morning, when my wife alerted me to the fact that the new

boiler was not running, from the comfort of my bed I was able to

say: ‘Alexa, please switch the heating on’. She did.”
